Cameron McIntyre, the chief executive of Carsales, says there are plenty of similarities between the car markets of Australia and Brazil, where the $8.7 billion ASX group has just increased its stake in local online classifieds leader, Webmotors.

But there are a few differences, too. In a country where personal safety can be a little dicey, mum and dad sellers are reluctant to hand out their home address to buyers. And where Aussie car owners might pimp their ride with a new sound system or mag wheels, Brazilians have other priorities.
